Onward and upward with “had got”

I have noted the New Yorker’s insistence on having its writers use the British “had got” instead of American “had gotten.” But the magazine seems to have kicked things up a notch; now, people being quoted are required to use it as well. In an April 25 profile of Reed Krakoff, CEO of Coach Leather, Krakoff recalls a period when “I had got poison ivy on my hands.”‘ I submit that every American, of which Krakoff is one, would have said gotten. Anyone disagree?
